As I see it, the problem of a robot in a workplace is that it's hard to integrate into a processes built around humans. But once you manage to bring some robots in, that factor will revert and now there will be much more straightforward to add more robots - a human will now be seen as a misfit that needs completely different scheduling. The actual difference is that robot usually does only one thing, and any limitations and deficiencies will need to be taken care of by human workers. Whereas a human needs all kinds of breaks throughout the day, needs conditioned workplace, unreliable in terms of durations and frequencies.
